PAPER-MAKING ROLL.

SPECIFICATION forming part of Letters Patent N o. 247,632, datedDecember 22, 1903. Application led September 16, 1902. Serial No.123,602. (No model.)

To all whom it may concern,.-

Beit known that I, HOWARD PARKER, a citizen of the United States ofAmerica, residing at Nashua, in the county of Hillsboro and State of NewHampshire, have invented .certain new and useful Improvements in Paper-Making Rolls,of which the followingisa specification.

The object of the invention is to produce a io device of the classspecified having features of novelty and advantage.

Figure l is a perspective view of a roll, partly in section, embodyingmy invention; Fig. 2 is a central vertical section of the same.

:5 Fig. 3 is a detail view, on enlarged scale, of

the sleeve. Fig. 4 is a detail view, onenlarged scale, of the core. Fig.5 is a detail view of the core-adjusting mechanism.A

I have shown my invention embodied in zo what is commonly called acouch-roll.7 The roll itself may be of any desired construction, havingthe perforated surface and lengthwise compartments formed by suitablepartitions. The shell of the roll is supported by flanges z5 b b',projecting from a tubular sleeve B. Se-

cured to these flanges b b are tubular pieces b3 b3, forming thejournals on which the roll rotates. The tubular sleeve B is made up ofthe cylinder b2, ateach end of which are sego cured the conical endpieces b b, which terminate in the flanges b b. These conical ends b bare slotted, as shown at bx bx, and on these conical ends between theslots rest the partitions which form the longitudinal compartments inthe roll. Thus each compartment has opening into it one of the slots bx.

The roll A, mounted on the sleeve B, rotates upon the core C. This coreC is made up of a pipe D. To one end of this ,pipe is 4o secured theconical head c, adapted in size and shape to fit the interior face ofthe conical end b of the sleeve B. On the other end of the pipe D islocated a similar conical head c', which is mountedto slide lengthwiseof the pipe and is keyed thereto, as at d. The outer end of the conicalhead c is closed by the cap E, having the recess e and a suitablestuffing-box 2. To the end of the pipe D is secured the cap K,- Vhavingahub la. This cap is perforated, as clearly shown at y in Figs. 2 and 4.The interior Wall of the pipe D is grooved, as at G, and in this grooveis located the collar H, adapted to slide length- Wise of the pipe. Thebolt F passes through an aperture in the cap E, through the hub la, andis screw-threaded onto the collar H, having a shoulder e', which fitsinto the recess e in the cap E. Between the hub 7c and the collar H,surrounding the bolt F, is the spring f. `A suitable stuffingbox isprovided at Z. Suitable perforations are made through the YWall of thepipe D, as at Figs. 2 and 4, in

order to afford communication between the interior of the pipe and theinterior of the head c. The head o terminates in the pipe M, which isconnected with a suitable suction apparatus. The heads c c' are slotted,as at eX ox, for about one-half of their circumference. It is clear thatthere being a suction action generated inside of the core C by suitablesuction apparatus connected at the end of the pipe M the differentcompartments in the roll A as it rotates about the core C will besubjected to the action of the suction as the slots bx register with theslots 0X.

It Will be seenfrom a careful inspection of the arrangement of the headc' with respect to the pipe D that the springf tends to draw thelconical heads c o' continuallytogether and to a close fit Within theconical ends b b of the sleeve B, thus insuring a perfect contactbetween the rotating and non-rotating parts and preventing the breakingof the suction at this point.

The roll A is driven by suitable gearing, as at b4.

It is oftentimes desirable to change the point at which the suctionaction shall begin to take eect upon the surface of the roll A, and inorder to do this I provide means whereby the core C may be rotatedwithin certain limits. The devices of which I make use comprise thecollar P, secured to the end of the pipe M and having a handle Q, with aprojection R, coacting with suitable notches S. It is clear that thisarrangement permits .of

turning the core by sim ply releasing the engagement of the projection Rwith one of the notches S and that the core is held in any desiredposition by the engagement of the projection R with one of the notchesS.

I claim as my invention- 1. In a roll for paper-making and like ma pchinery the perforated shell carried by a suitable sleeve, the core uponwhich said sleeve rotates and coacting conical bearing-surfaces on' thesleeve and core on which said roll revolves, substantially as described.

2. In a roll for paper-making and like machinery the perforated shellsupported on a sleeve having conical ends, and the core having conicalheads adapted in shape and size to lit the conical ends of the sleeveand permit the roll to revolve thereon, substantially as described.

3. In a roll for paper-making and like machinery lthe shell carried by asleeve, said sleeve having outwardly-flaring conical ends, a core uponwhich said roll rotates, said core having outwardly fiaring conicalheads adapted to fit the conical ends of said sleeve, said conicalportions of the sleeve and core constituting the bearing on which theroll rotates, and means for maintaining close contact between theconical ends of the sleeve andthe conical heads of the core,substantially as described.

4. In a machine of the class specified the roll mounted on a sleeve,said sleeve having conical ends, the core provided with conical headsfitting the conical ends of said sleeve and on which said roll rotates,the conical heads of said core being adapted for movement toward andaway from each other, substantially as described.

5. In a device of the class specified the roll carried by a sleevehaving conical ends, the core having conical heads adapted in size tothe size of the conical ends of the sleeve and forming a bearing onwhich said roll and sleeve rotate, slots through the conical ends of thesleeve and through the conical heads of the core, and means for rotarilyadjusting the position of said core, substantially as described.

6. In a device of the class specified in combination the roll, thesleeve carrying said roll and having outwardly-flaring conical ends, thecore comprising a pipe having a conical head securely attached theretoat one end, and a second conical head located at the other end andadapted to slide lengthwise thereof, and compensating mechanism betweenthe pipe and the sliding conical head, substantially as described andfor the purposes set forth.

7. In a device of the class specified, the stationary core, therotatable roll supported by a tubular sleeve which rotates on said core,openings through Athe core and the tubular sleeve adapted to registerwith one another, and means for rotarily adjusting the position of thecore, substantially as described.

In testimony whereof I afx my signature in presence of two witnesses. v
